The author supposed previously that glucose-6-phosphate plays an important role in glycolysis as it is found in high level in the muscle of seabass. On the other hand, glucose-6-phosphate produces brown color by the reaction with amino acid. Therefore, glucose-6-phosphate in muscle is an important compound not only in physiology but in food processing. The present paper deals with phosphoglucomutase which catalyses the reaction, G-1-P ?? G-6-P. Caudal muscle showed the highest activity of phosphoglucomutase and ventral muscle showed the lowest. Loss of the enzyme activity by the change of freshness of muscle was slow. After storage of 2 days at 25°C, 47% of the enzyme activity was found. Optimum temperature for the enzyme action was 45°C, and the activity was found to cover a wide range of temperature. The influence of the reagents such as urethane, CTC, nitrofurazone and sodium chloride on the enzyme were not so clear.
